Abstract

The present invention relates to an electic coffee machine and a filter element (1) therefor. The coffee machine includes a filter element (1) for taking up ground coffee (12) that is supported by a filter housing. A brewing head (2) is provided above the filter element (1) and has one or a plurality of outlet openings (3) from which water (14) heated by an electric water heater flows into the element (1) in order to extract the coffee. According to the present invention, the filter element (1) includes on its outside top edge (9) an annular collar (10) which extends at an angle relative to the edge (9). The filter element (1) is made of filter paper. Disposed below the annular collar (9) is a securing device (28) which bears the filter element (1) and on which the filter element (1) is supported in a substantially cantilevered manner. In this way, the filter element and the coffee machine are easier to handle. In addition, brewing results are improved and the dripping time is reduced.
